What is CLLC Converter with Battery in MATLAB Simulink | Modeling & Simulation?
CLLC Converter with Battery in MATLAB Simulink | Modeling & Simulation is a MATLAB-based technical project and simulation model. A CLLC resonant converter is an isolated DC-DC converter topology that can provide bidirectional power transfer between a DC bus and a battery energy-storage system. Its resonant network enables soft-switching operation, which can reduce switching losses and support high-frequency operation. These characteristics make bidirectional CLLC converters attractive for battery energy-storage and electric-vehicle charging applications. In this project, a CLLC converter with a battery is modeled and simulated in MATLAB Simulink to investigate battery charging and discharging operation. The model can be developed with a high-frequency full-bridge stage, CLLC resonant tank, high-frequency transformer, secondary-side bridge, DC-link/battery interface, and closed-loop controller. Frequency modulation is commonly used to regulate power flow through the resonant network
